摘　　要：电力系统二次设备有着大量的板卡插件等弱电电子电路,很多二次系统的故障隐患均是来自于这些弱电电子系统的外部干扰、外部交流侵入、接地电流干扰等,因此对于这些设备的绝缘检测,就显得尤为必要。对此提出了专门针对二次板卡插件等弱电设备的绝缘检测方法,力求用安全的低电压检测板卡插件设备的绝缘缺陷。The secondary equipment of power system has a large number of board plugins and other weak electronic circuits.Many hidden faults of the secondary system have arisen from the weak electronic system,such as the external interference,external AC intrusion and grounding current interference,etc.Therefore,the insulation monitoring of these devices is particularly necessary.In this paper,a special insulation monitoring method for weak current equipment such as secondary board plugin is proposed,whereby the insulation defects of board plugin equipment are detected with safe low voltage.
